Carbon Monoxide (CO) Sensor (MQ-7)

Follow the pictures and diagram below to wire up and code the CO sensor. When you have the device ready, go to the tools menu at the top and turn on the Serial Monitor (slide 4). This will let you see how much CO is in the air.

Humidity & Temperature Sensor

Code and wire up the temperature and humidity sensor. You may need to download and then import the DHT file below for it to work.Remember to open the Serial Monitor like you did in the last project. You will also need to look at the Serial Monitor in order to see the temperature and humidity results once your device is running.

UV (Ultra Violet Light) Sensor

Weather Station 1

Follow the wiring schematic below to wire the sensors to the Arduino Uno correctly to build a mini weather station. Then type in the code as shown. Notice how the code from the previous projects were placed (combined) all together so that data can be collected simultaneously. Do not forget to watch the data appear in the Serial monitor. Serial Monitor is located in the tools menu.

STEM

Engineering

Design an Enclosure that will accommodate a full size breadboard, Arduino uno and battery pack, while allowing sensors to protrude.

Use 3D printer or other materials such as cardboard, wood, styrofoam or plastic.

Create a drawing of your first prototype enclosure and device.

Extended Design: Advanced Weather Station; learn how to incorporate an SD Card for recording data, other gas sensors, include on board long range wifi module or GPS tracker as well as an impact proof enclosure. Also consider and design a system for attaching a weather ballon for launching your advanced weather station into the sky. Research protocols for weather balloon launches.
